Title: Procedure for the manufacture of a foamed plastic product
Inventor: KIRJAVAINEN KARI
IPC: C08J9/00
Filed: 1995-08-16
Abstract: Procedure for the manufacture of a foamed plastic product, in which procedure a filmlike plastic product (1) is perfoamed e.g. by using foaming agents added into the manufacturing process, in such a way that lamellar discontinuities (2), e.g. prefoamed bubbles, are created in the product (1). The product (1) is pressurized with a desired gas, such as nitrogen or air, under positive pressure, causing the gas to diffuse into the product. The product (1) is then inflated by sujecting it to a heat treatment under reduced pressure during which the product is heated at a temperature below its melting point.

Patent CA-2198765-A1 (CA)
Inventor: KEN CHRISTOPHER G M
IPC: A61F2/00
Filed: 1997-02-27
Abstract: This is an implantable vaso-occlusive device. It is typically a vaso-occlusive coil comprising a primary helically wound coil which may then  be wound into a secondary shape. Central to the invention is the use of a stretch-resisting member extending through the lumen formed, which stretch - resisting member is fixedly attached, directly or indirectly, to the coil in at least two locations. The stretch resisting member is preferably somewhat loose within the interior of the lumen so to prevent the coil from collapsing, binding, and t herefore stiffening during passage of turns through the human body. The coil should b end easily. In some variations of the invention, the stretch-resisting member ma y beformed into coil tips at the ends of the coil using simple equipment such as soldering irons or the like. The tips are typically of the same diameter as is the coil body itself. This stretch-resisting member is for the primary purpose o f preventing stretching of the coil during movement of that coil, e.g., by ret rieval or repositioning after deployment. The device may have a self-forming secondary shape made from a pre-formed primary linear helically wound coil, although i t need not have the secondary form. Desirably, the coil is extremely flexible and is controllaby released using a severable or mechanical joint such as an electrolytically detachable joint. External fibers may be attached to the de vice and affixed to the pre-formed linear member to increase thrombogenicity. The extremely flexible variation of the invention may be hydraulically delivered through the lumen of a catheter and is so flexible that it may be retrievabl y delivered therethrough a flow-directed catheter. The vaso-occlusive member m ay be also be covered with a fibrous braid. The device is typically introduced intothe body through a catheter. The device is passed ax ially through the catheter sheath and assumes its secondary form upon exiting the catheter.

Patent CA-2211477-A1 (CA)
Title: Voltage controlled attenuator
Inventor: GARRETT CAREY M
IPC: G02B6/26
Filed: 1997-07-24
Abstract: A voltage controlled attenuator for an optical telecommunication system comprises an optical attenuator placed between an input and an output lens for obstructing the path of an incoming light beam. The attenuator has variable attenuation (reflection, absorption, etc.) which is controlled for maintaining a preset power of the outgoing light beam. To this end, a fraction of the outgoing signal is diverted to an output detector by reflecting off an end face of a lens, and processed for obtaining a control signal representative of the output power. The control signal actuates a dc motor which displaces the attenuator to a position corresponding to a preset output power.

Title: Induction heating system for fusion bonding
Inventor: DONOHO HAROLD FINIS JR
IPC: B29C65/36
Filed: 1996-02-12
Abstract: An induction heating system for fusion bonding, particularly useful in the sealing of telecommunications cables and closures, comprises a composite bonding material having a bonding matrix and susceptors, the susceptors being magnetically reactive at a frequency above 50 MHz, and an applicator for applying radiant electromagnetic energy to the composite bonding material, at a frequency above 50 MHz (preferably 75-500 MHz). The applicator may take the form of a quarter-wave resonator having an inner conductor and an outer conductor which at least partially surrounds the inner conductor, the two conductors being shorted at a common end. The material to be heated is placed between the conductors. The inner conductor may include a resonator tube which is capacitively coupled to the power supply by a capacitive probe connected to the center conductor of a coaxial connector. Different applicators (having different geometries) may be used with the same power supply, or a variety of heater adapters may be provided which can be removably attached to the applicator base. An alternative applicator employs many wires, electrically insulated from one another, each forming a coil with a common axis, and all of the wires being electrically connected in parallel. Several of these wires are stacked to form multiple layers of coils, such that the effective resistance of said applicator is reduced and the current-carrying capacity is increased. Individual capacitors may be connected in series with a respective one of the wire coils, to make the current in the coils more uniform for coil circumferences which are greater than 0.1 of the wavelength of the radiant electromagnetic energy.

Abstract: Determining for each base station in a wireless telecommunication switching system whether a wireless handset should receive audio or vibration alerting for incoming calls. The wireless telecommunication switching system utilizes information specifying alerting for the base stations that is entered by a system administrator. In addition, individual users may choose to specify areas designated by the system administrator for audio alerting as vibration alerting. The information specifying the audio or vibration alerting from either the administrator or individual users is specified for different periods of time for each of the base stations. The system administrator may directly determine the alerting information for each individual base station. Also, the system administrator may determine the alerting information for different areas of the building, and as base stations are added to the wireless telecommunication system, they inherit the attributes of the area in which they are placed.

Title: An arrangement for sensing elastic deformation in a tool stem in a machine tool
Inventor: ERICSSON CLAES
IPC: G01B11/16
Filed: 1996-10-23
Abstract: There is shown an arrangement for detecting elastic deformation of a tool shaft carried by a machine tool and, in turn, carrying a cutting bit. An optical fibre section is mounted in or on the shaft at a distance from its neutral bending line in the longitudinal direction of said shaft. The optical fibre section, which follows the elastic deformation of the shaft, extends parallel with and at a constant distance from the neutral bending axis of said shaft, so that elongation of the fibre section forms a measurement of bending of the shaft in an axial plane that includes the optical fibre section. The optical fibre section has at least two longitudinally spaced partial reflection means and means are connected to the optical fibre section to determine interferometrically a change in distance between the partial reflection means in the optical fibre section, wherein the change in distance forms a measurement of shaft curvature between the two partial reflection means. The arrangement also includes means for compensating for the influence of temperature on the change in distance between the partial reflection means.
